PREVENTION OF THE FORMATlON F MOLD AND WHITE FlLl/l ON FERMENTABLE ANDFERMENTED uoums.

SPECIFICATION forming part of Letters Patent No. 351,299, dated October19, 1886.

Application filed May 27, 1856. Serial Kn. 203.469. (No specimens.)Patented in Germany May 1l,1884, No. 30,451.

To aZZ whom it may concern:

Be it known that I, JoiLiNN PETER ADOLF VOLLMAR, a citizen of the GermanEmpire, residing at Kcmpteu, in the Grand Duchy of 5 Hesse and GermanEmpire, have invented new and useful Improvements in the Prevention ofthe Formation of Mold and XVhite Film on Fermentable or FermentedLiquids, of which the following is a specification.

The object of this invention to provide means for preventing theformation of fungus, mold, or similar matter, particularly in or onfermentable or fermented liquids.

In the years 1877 and 1878 Doctor Nesslcr published a means intended toguard against the formation of fungus, mold, or similar matter in or onliquids, said means consisting of small pieces of wood saturated with,paraffiue mixed with salicylic acid, said pieces of wood so preparedbeing spread over the surface of the liquid. It was considered thatthese floating masses, when placed in filled barrels,would float on thesurface of the contents of the barrels, and that as the contents weredrawn off and the surface varied the floating masses, would continuallyform a protecting cover on the surface and prevent the entrance into theliquid of spores, which enter the barrels with the air. This last-namedmethod, as also other forms of floating wood, have notproved practicallysuccessful, because by the movement of the surface on which they floatedthese floating particles come to rest over or under one another or tocling to the walls or sides of the barrels. In this way breaks oropenings are formed in the protecting-cover.

The method I adopt is to form small spheres or spherical bodies of waxhaving about five millimeters diameter. These spheres or sphericalbodies will not rest under or over one another, nor will they cling tothe walls or sides of the barrels. Breaks or openings in the protectingcover or layer are thus avoided. The wax is made antiseptic by beingimpregnatcd with sulphurous acid or by being mixed with acid sulphuroussalts--as, for example,

soda salt or potash salt; or the wax may be mixed with salicylic acid.The sulphurous acid may be easily obtained by the action of copper uponsulphuric acid. The mixing of the various substances with wax canreadily be accomplished when the waxis melted or softened.

Vith regard to the use of salicylic acid as an antiseptic, I would statethat according to some opinions hygienic objections have been raisedagainst its use, and said objections have in their turn beencontroverted.

By the method which I have set forth, salicylic acid can be employed ornot, as may prove to be of advantage.

The wax impregnated or mixed with antiseptic, as above set forth, isrolled or formed into balls or spherical masses. Thisformation of ballsor spherical bodies can be accomplished by rolling or by means of apill-machine, which cuts or presses small particles of the material.

The pills or spherical bodies may be prepared as follows: Finely-scrapedwax is mixed or kneaded with sulphurous acid, and the mix ture ispressed or formed into sheets. The sheets are cut into particles ofsuitable size, and by means of any suitable well-known mechanism saidparticles are rolled or formed into balls or given a spherical form; or,in

'place of the method just described, I can i1npregnate cork -dust orfinely-disintegrated cork with sulphurous acid and mix the impregnatedcork with wax. By softening the Sc wax the mixing can be readilyaccomplished. This mixture is then pressed or formed into sheets andsmall balls are formed therefrom,

as above set forth.

In place of sulphurous acid, I can employ other antisepticsas, forexample, sulphite of lime, sulphite of potash, or salicylic acid, eitherdry or dissolved in any suitable solvent.

Care must always be taken that the completed pills will be of lessspecific gravity than 0 the liquid which they are to protect, so thatsaid pills or balls will float on the surface of the liquid. The waxwhich is used as a base for the pills should be pure, or at any ratefreed from all septic substances.

In place of wax, it is evident that I can employ any other non-absorbentof moisture having a sufficiently light specific gravity-ms, forexample, paraiiine.

Instead of forming sheets of the complete 100 material and cutting saidsheets into particles fermenting liquids by applying thereto pills andforming said particles into balls or pills, or spheres composed of anon-absorbent base, I can also form the balls or pills by a so calledsuch as wax, and an antiseptic, such as 5111- i pill-machine. By passingthe completed phurous acid. v I 5 l 5 material through a press-cylinder,small bars In testimony whereof I have hereunto set my of any desireddiameter can be formed, which hand and seal in the presence of twosubscribbars can then be cut or severed and rolled or ing witnesses.

formed into pills or spherical masses. JOii. PETER ADOLF VOLLMAR. [L. s]
